The module receives digital control commands from the main controller via internal bus. The isolation circuit transmits signals to drive units, which output 24 V DC switching signals to external solenoid valves, contactors and other actuators. Once over-current or short circuit occurs, the protection circuit immediately cuts off the faulty channel and triggers status alarm.
- Independent protection for each channel, prevent chain fault spread
- Stable load driving capability for common low-power industrial actuators
- Excellent anti-vibration and anti-interference performance
- Modular plug-and-play design for easy replacement and maintenance
- Wide temperature range for diverse industrial working conditions
Hydraulic & pneumatic control, packaging machinery, printing equipment, automation assembly, metallurgy auxiliary equipment, environmental protection equipment
- Install on standard 35 mm DIN rail inside industrial control cabinet
- Keep unobstructed heat dissipation grooves, no coverage or blockage
- Power lines and output signal lines shall be routed separately
- Complete reliable protective grounding in accordance with industrial standards
- Keep distance from heat sources and high-frequency interference equipment
- Do not connect loads exceeding rated 0.5 A per channel
- Perform all wiring operations under power-off state
- Regularly clean dust on shell and terminals every 3 months
- Do not use in environment with flammable gas or explosive dust
- After channel protection tripping, eliminate fault before restart operation
